Shark Study Reveals Taste Buds were Key to Evolution of Teeth
While human taste buds sit individually on the tongue, numerous creatures’ specifically non-animal vertebrates have taste buds that line the areas of the jaws that likewise house teeth. The areas of a shark's mouth with the most astounding attentiveness of taste buds are right behind the last line of teeth in both the upper and lower jaws, indicating a significant relation amongst biting and tasting. These undifferentiated cells additionally oversee the teeth's capacity to recover throughout the shark's life, and it turns out the shark's taste buds likewise share this capacity. We realize that taste buds developed in primitive fishes before oral teeth because taste bud-like structures are existent in jawless fishes such as lampreys. So if denticles migrated into the mouth and progressed into oral teeth, their evolution may have turned out to be connected with that of taste buds, creating from similar cells and adopting their regenerative capacity.

Also the teeth share evolutionary history with skin denticles even though both dentine and enamel have numerous differences. For instance shark denticles cannot restore like their teeth. Additionally learning how genes are not in shark denticles but are in oral tooth growth, regeneration, and taste buds. My behavior has altered towards sharks I have always thought they were just big fishes that didn’t have any interesting genetics. I had chosen this article initially because I have swam with sharks previously and they seemed harmless. Probably because they were baby sharks. So it interest me to know why there are so many topics about their teeth that make them look
